Vegetable planting technology refers to the planting and management process is strictly regulated, strict management of external factors, in accordance with the relevant standards for the use of fertilizers, pesticides, scientific control of pests and diseases of safe vegetables, so that the planting of the vegetables is relatively safe and reliable, its heavy metal content is low, no serious pesticide residues, will not affect human health.

1, seed treatment

In the process of vegetable planting, seed selection and treatment is also crucial, the yield and quality of vegetables have a great impact. Choose high-quality vegetable seeds, ensure that the vegetable seeds themselves have a strong resistance, thus reducing the subsequent planting procedures, thus avoiding a large number of pesticide residues in the vegetables, and reducing the impact of pesticide residues on the health of people who eat them.

Appropriate treatment of seeds before sowing, to ensure the rationality and scientificity of the treatment method, so as to improve the resistance of sowing and reduce the occurrence of pests and diseases. Choose a reasonable nursery location, strengthen the control of pests and diseases, and reduce the impact of pests and diseases on the nursery work. In addition, the soil must be treated before sowing to ensure that the soil meets the growth requirements of the seeds, thus ensuring the normal growth of the seeds.

2, the use of fertilizers

Vegetables have a high demand for nutrients, and relying on the nutrients in the soil alone will not satisfy the growth needs of vegetables, and it will lead to a lack of the necessary assurance of the quality of vegetables. Therefore, attention must be paid to the application of fertilizers to provide vegetables with the necessary nutrients to ensure the normal growth of vegetables and improve the quality of vegetables. Choose the right fertilizer, ensure the rationality and scientificity of fertilizer selection, at the same time, pay attention to the matching of fertilizers, reasonable mix of organic fertilizers and inorganic fertilizers, to promote the growth of vegetables.

3, the use of pesticides

Pesticides play an important role in the growth of vegetables. Reasonable use of pesticides can improve vegetable yield and maximize economic benefits. However, it is worth noting that excessive use of pesticides can cause a large number of pesticide residues on vegetables, threatening the health and safety of consumers. Therefore, attention should be paid to controlling the amount of pesticides to ensure that the amount of pesticides is reasonable.

? In addition, attention should be paid to the choice of pesticide varieties, try to use low-residue pesticides, to reduce pesticide residues under the premise of ensuring the effectiveness of pest control, to ensure the safety of vegetables. To pay attention to the choice of pesticide use time, to grasp the pattern of pests and diseases, as soon as possible to carry out pest control work, reduce the use of drugs.

4, irrigation management

Irrigation management is the key to vegetable management, a greater impact on vegetable production. In carrying out irrigation management, according to the actual situation to develop a scientific and reasonable irrigation plan for the growth of vegetables to provide stable and reliable water resources, pay attention to water quality management, to ensure that the water quality is clean, to avoid the impact on the vegetables. According to the characteristics of the vegetables to carry out irrigation work, and according to the soil, climate and other external factors to make appropriate adjustments to the irrigation work, to ensure that the irrigation work is scientific and reasonable. It is worth noting that the same kind of vegetables in different growth stages of water demand may also be very different, so planting should pay attention.
